In the past I've spend hundreds of dollars testing on AdWords figuring out what some of the new or 'hidden' features are. Now I just post in Certified Knowlege. Within hours (sometimes minutes) I get a reply from one of the most knowledgeable AdWords men on the planet ( & that includes most people that work for Google).
One recent post more than paid for my membership for the next 3 months.
